[solved] Ethernet doesn't have a valid IP configuration

So... I just updated from win 7 to win 10, as I got it for free. All went smoothly, but there was no ethernet connection. I'm running a custom built pc, connected to my router via ethernet cable.

At first windows detected the cable, but said: ''Ethernet doesn't have a valid IP configuration." I was on about around the settings, and deleted the ethernet network from windows' settings. I thought it would come back by just re-plugging the cable. This didn't happen. What happened was, that the whole 'Ethernet' tab disappeared from the 'Network & internet' menu!

I also don't have 'Wi-fi' or 'Airplane mode' tabs in the menu... Well I have a pc that doesn't have support for wifi so that might be why...

Does anyone have a clue on how to get win 10 to detect the ethernet cable, and maybe that way bring back the 'ethernet' tab?

Oh, and I tested the ethernet cable on my laptop (running win 7), and it worked fine.


Thanks in advance!

have you tried disabling and enabling the ethernet from device manager?

in run box type ncpa.cpl
and let us know if you see Network connection icons if no, reinstall ethernet drivers if yes what does it say, (unidentified, No access etc)
Are you directly connected to Modem or is there a router is between.

Well, I got it fixed... Should have thought of updating the drivers earlier, I guess it was kinda obvious. It's pretty hard though, to download drivers from the internet, without an internet connection... Plugged my phone to the computer via usb, and shared the phones internet connection.

If someone else has the Ethernet tab missing, I got it back by going to Control panel - Network and sharing center - 'change adapter settings' there I re-enabled the ethernet connection I had deleted earlier.

I had the same problem. I upgraded from a perfectly working Asus M32 running Windows 8.1 to Windows 10. After the install I had no internet connection and the troubleshooter told me "ethernet doesn't have a valid IP configuration". I uninstalled my Intel Ethernet driver by going to the control panel>device manager>network adapters>Intel Ethernet Connection 1217-V>right click>uninstall>OK. I used my other computer to download the driver and reinstalled it. BOOM! Internet connected. I don't know if the problem is with Intel ethernet drivers or others. Regardless of the brand... reinstall the ethernet driver. (:-)V(:-) Intel Download Center

That's why I recommend to download any drivers beforehand when upgrading to a new OS. I have had this problem myself in the past, so I now know and advise others to download any drivers beforehand.

Always a great idea. I keep a flash drive updated with drivers and important apps. This way, if I ever need to reinstall or set up a new machine, what I need is readily available.

This worked today on my Windows 10 Anniversary

Thanks

I copied the install file for the update to Realtek PCIe GBE Family Controller, but Windows won't allow the install, says the correct driver is already installed ( Realtek PCIe FE). I've also tried diagnostics, config release and renew, no help at all. Any other ideas?
